I used them in a 3 axis Arduino CNC build. The position and tolerance of the most important center line was exactly according to the specifications, but there were no tolerances for the less important dimensions. Following the 5mm hole spacing specified in the spec, I had no problem screwing them onto the panels I machined. I have found that most other product sizes are +/- 1mm or possibly more so be sure to leave enough clearance. Check the alignment of the critical assembly with the display.
